📁 Case Management
Every panel resolves local-first: threat, category, first-seen & sightings from
indicators; DNS from dns_records; WHOIS from whois_cache; subdomains via bounded suffix match on indicators; related IPs from A/AAAA records; tags, reporting sources and the link graph from the local relations. Live OTX pulses and DNS-over-HTTPS are optional augmentation and their absence never blanks the dossier.
